the following ingredients, combined in sub-.

stantially the proportions stated, to wit:

China wood oil 72% Chlorid of sulfur 8% Grid of magnesium 7% Comminuted cork 13% I am aware that a composition consisting of corn oil, chlorid of sulfur and oxid of magnesium has been used for the same purpose, and that Patent Number 1,174,856 was granted to Frank A. Hager therefor on March 7, 1916; and I am also aware that various oils have been used in compositions for the same purpose.

1 have discovered, however, that China wood oil in combination with the above ingredients results in a product of greater resiliency and lighter weight, as well product of more durable character than has been produced by the use of other oils.

Specification of Letters Patent.

as a

Patented Feb. 113, 191% Application filed April 26, 1916. Serial No. 93,771.

I have also discovered thatthe use of a proper percentage of comminuted or powdered cork introduced into such a composition results in a product of greatly decreased weight without detriment to those other necessary characteristics, resiliency and durability.

In preparation, the ingredients of my composition are thoroughly mixed, and then molded into the desired form.

' In use, the molded product is firmly in cased within the outer casing commonly used with pneumatic tires, thus eliminating the inner tube and compressed air.

Having disclosed my invention so that others skilled in the art may be enabled to construct and use same, what I claim as new, and desire to secure by Letters Patcut, is:---- A tire filler comprising the following ingredients in proportions substantially as set forth: China wood oil 72%; chlorid of sulfur 8%; oxid of magnesium 7%; comminuted cork 13%.

In witness whereof I claim the foregoing as my own I hereunto affix my signature in the presence of two subscribing witnesses, at Portland, county of Multnomah, State of Oregon, this 20th day of April, 1916.
